Permission denied with PutFile

[Brian_techguy]

All: I'm struggling to get a PutFile to work. (See verbose output
below; admin_key blanked out). I'm working with a v2 wiki and believe
I have it API-enabled (checked 'Enable developer interface' on my wiki
settings) and am using the correct admin_key. I'm using curl on a
Windows XP Pro machine.

curl -v -Fdata=@curl.txt http://bennbrian.pbwiki.com/api_v2/ -
